What is one of the main outcomes of increased permeability during inflammation?

• A. Reduced blood pressure
• B. Clotting proteins leave the bloodstream
• C. Decrease in immune cell migration
• D. Fast recovery of tissue

Answer: (B)

Increased permeability during inflammation allows proteins and other molecules to pass through blood vessel walls more easily. This phenomenon is crucial during the inflammatory response, as it enables clotting proteins to exit the bloodstream and enter the affected tissue. The presence of these proteins helps to form a stable clot at the site of injury, preventing further bleeding and providing a scaffold for new tissue formation as the healing process begins. This mechanism enhances the overall defense against pathogens and promotes tissue repair by allowing necessary components involved in the healing process, such as antibodies and clotting factors, to reach the affected area.

In contrast, reduced blood pressure is not a direct outcome of increased permeability, as blood pressure might fluctuate due to various other factors during inflammation. While immune cell migration typically increases during inflammation to respond to threats, the increased permeability facilitates their movement rather than decrease it. Lastly, while inflammation initiates healing, it does not guarantee a fast recovery of tissue; the process can sometimes be prolonged depending on the severity of the injury and the overall health of the individual.
